DNA Gatherers Hit a Snag: The Tribes Don’t Trust Them

The National Geographic Society’s multimillion-dollar research project to collect DNA from indigenous groups around the world in the hopes of reconstructing humanity’s ancient migrations has come to a standstill on its home turf in North America.

Billed as the “moon shot of anthropology,” the Genographic Project intends to collect 100,000 indigenous DNA samples. But for four months, the project has been on hold here as it scrambles to address questions raised by a group that oversees research involving Alaska natives.

At issue is whether scientists who need DNA from aboriginal populations to fashion a window on the past are underselling the risks to present-day donors. Geographic origin stories told by DNA can clash with long-held beliefs, threatening a world view some indigenous leaders see as vital to preserving their culture.

They argue that genetic ancestry information could also jeopardize land rights and other benefits that are based on the notion that their people have lived in a place since the beginning of time.
